Thank you to all of you that were so willing to help. New cap, opened the valve took a drive with it open, got up to temp and shazaam no more leak. Thank you all so much.
I just installed topspeed test pipes and new aftermarket muffler literally just before this leak problem showed up. So anyone want to take a guess what I will be doing this weekend?
Thanks Porsche Brethren!
to you all!
